Arch Linux User Repository

A few problems with the package :

• The install script try to modify the user .bashrc (or .zshrc) but it's executed in root context (sudo pacman -S) so it will not work. Better to leave an informative message and leave it to the users
• There is png / gif which are packaged with the script, wasting some space
• The script should be in /usr/share (like for example bash-completions)

Here is a patch that fix those (applicable with git am):

Subject: [PATCH] Remove .bashrc modif in install script

- The .bashrc modif is executed in root context, so it would not achieve
  the intended purpose
- Put the script in /usr/share/ , like bash completions
- Get rid of unneeded images which were packaged (examples image from
  the source).
